In industry, the tube in tube heat exchangers are used as condensers, vaporizers, sub-coolers, heat recovery exchangers, crystallizers etc. Much work has been done on tube with fins, corrugated tube, insertion in tubes baffle arrangement and nano fluid used, but the performance can also be increased by changing the tube geometry, which was designed to increase the performance of the heat exchanger. In this research work, a double tube heat exchanger of circular and elliptical tube is modeled and numerical simulation as well as CFD simulation have been done to enhance the performance of heat exchanger. Analytical result of Circular tube heat Exchanger validate by the CFD results and found that 0.059% variation in temp, which is acceptable. Comparission of CFD simulation done for Double tube heat Exchanger of Circular and Elliptical tube have been done and found that the elliptical tube geometry is better heat transfer than existing circular double tube heat exchanger.

This paper studies the different heat transfer enhancement technique, to find out the some new technique for enhancement of heat transfer rate. Introduction The energy conservation is one of the most vital issues in current century, and it will certainly be one of the most significant challenges in the near future. Therefore, scientists are considerably trying to address this important concern. The advances made in heating or cooling in industrial devices cause energy saving and heat transfer improvement, and increase the operational life of the equipment. Energy savings can be performed by the efficient use of energy. Energy conversion, conservation and recovery are some routes for energy saving. To above mentioned purpose, various types of heat exchangers are utilized in many industrial areas such as power plants, nuclear reactors, petrochemical industry, refrigeration, air-conditioning, process i...
